A common class of chemicals that’s been linked to cancer, fertility problems, and thyroid dysfunction has now been tied to another major health issue: According to a new study in PLOS Medicine, women who have high levels of perfluoroalkyl substances (PFAS) in their blood tend to gain back more unwanted weight after dieting.

The new study included both men and women who’d been enrolled in a two-year clinical trial and who lost weight by following a heart-healthy diet. But when researchers factored in the levels of PFAS in participants’ blood at the start of the study, they found that people with high levels tended to gain more of that weight back after initially losing it.
